453380318e s390/cpumf: Allow multiple processes to access /dev/hwc
Commit a029a4eab3 ("s390/cpumf: Allow concurrent access for CPU Measurement Counter Facility")
added CPU Measurement counter facility access to multiple consumers.
It allows concurrent access to the CPU Measurement counter facility
via several perf_event_open() system call invocations and via ioctl()
system call of device /dev/hwc.  However the access via device /dev/hwc
was exclusive, only one process was able to open this device.

The patch removes this restriction. Now multiple invocations of lshwc
can execute in parallel. They can access different CPUs and counter
sets or CPUs and counter set can overlap.

3b051e89da s390: add support for BEAR enhancement facility
The Breaking-Event-Address-Register (BEAR) stores the address of the
last breaking event instruction. Breaking events are usually instructions
that change the program flow - for example branches, and instructions
that modify the address in the PSW like lpswe. This is useful for debugging
wild branches, because one could easily figure out where the wild branch
was originating from.

What is problematic is that lpswe is considered a breaking event, and
therefore overwrites BEAR on kernel exit. The BEAR enhancement facility
adds new instructions that allow to save/restore BEAR and also an lpswey
instruction that doesn't cause a breaking event. So we can save BEAR on
kernel entry and restore it on exit to user space.

26c21aa485 s390: rename last_break to pgm_last_break
With the upcoming BEAR enhancements last_break isn't really
unique, so rename it to pgm_last_break. This way it should
be more obvious that this is the last_break value that is

ada1da31ce s390/sclp: sort out physical vs virtual pointers usage
Provide physical addresses whenever the hardware interface
expects it or a 32-bit value used for tracking.

Variable sclp_early_sccb gets initialized in the decompressor
and points to an address in physcal memory. Yet, it is used
as virtual memory pointer and therefore should be converted.

Note, the other two __bootdata variables sclp_info_sccb and
sclp_info_sccb_valid contain plain data, but no pointers and
do need any special care.

3826350e6d s390/ap: Fix hanging ioctl caused by orphaned replies
When a queue is switched to soft offline during heavy load and later
switched to soft online again and now used, it may be that the caller
is blocked forever in the ioctl call.

The failure occurs because there is a pending reply after the queue(s)
have been switched to offline. This orphaned reply is received when
the queue is switched to online and is accidentally counted for the
outstanding replies. So when there was a valid outstanding reply and
this orphaned reply is received it counts as the outstanding one thus
dropping the outstanding counter to 0. Voila, with this counter the
receive function is not called any more and the real outstanding reply
is never received (until another request comes in...) and the ioctl
blocks.

The fix is simple. However, instead of readjusting the counter when an
orphaned reply is detected, I check the queue status for not empty and
compare this to the outstanding counter. So if the queue is not empty
then the counter must not drop to 0 but at least have a value of 1.

ASoC: dt-bindings: rename q6afe.h to q6dsp-lpass-ports.h
move all LPASS audio ports defines from q6afe.h to q6dsp-lpass-ports.h
as these belong to LPASS IP.
Also this move helps in reusing this header across multiple audio
frameworks on Qualcomm Audio DSP.

This patch is split out of the dt-bindings patch to enable easy review.

ASoC: dt-bindings: move LPASS clocks related bindings out of q6afe
q6afe (Audio Front End) is one of the DSP service that handles both
LPASS (Low Power Audio SubSystem) Audio ports and LPASS clocks.
As LPASS is a hardwware IP and commonly used by Qualcomm Audio DSP.
In order to allow  multiple DSP frameworks to use these bindings
its best to move it out from the dsp specific bindings.

For compatibility reasons and not breaking which is already working
we still maintain same compatible string "qcom,q6afe-clocks"

Also as part of this change convert these LPASS clocks related bindings
into yaml format.

2195f2062e nfc: port100: fix using -ERRNO as command type mask
During probing, the driver tries to get a list (mask) of supported
command types in port100_get_command_type_mask() function.  The value
is u64 and 0 is treated as invalid mask (no commands supported).  The
function however returns also -ERRNO as u64 which will be interpret as
valid command mask.

Return 0 on every error case of port100_get_command_type_mask(), so the
probing will stop.

72b93a8685 Merge branch 'mlxsw-rif-mac-prefixes'
Ido Schimmel says:

====================
mlxsw: Support multiple RIF MAC prefixes

Currently, mlxsw enforces that all the netdevs used as router interfaces
(RIFs) have the same MAC prefix (e.g., same 38 MSBs in Spectrum-1).
Otherwise, an error is returned to user space with extack. This patchset
relaxes the limitation through the use of RIF MAC profiles.

A RIF MAC profile is a hardware entity that represents a particular MAC
prefix which multiple RIFs can reference. Therefore, the number of
possible MAC prefixes is no longer one, but the number of profiles
supported by the device.

The ability to change the MAC of a particular netdev is useful, for
example, for users who use the netdev to connect to an upstream provider
that performs MAC filtering. Currently, such users are either forced to
negotiate with the provider or change the MAC address of all other
netdevs so that they share the same prefix.

Patchset overview:

Patches #1-#3 are preparations.

Patch #4 adds actual support for RIF MAC profiles.

Patch #5 exposes RIF MAC profiles as a devlink resource, so that user
space has visibility into the maximum number of profiles and current
occupancy. Useful for debugging and testing (next 3 patches).

Patches #6-#8 add both scale and functional tests.

Patch #9 removes tests that validated the previous limitation. It is now
covered by patch #6 for devices that support a single profile.

605d25cd78 mlxsw: spectrum_router: Add RIF MAC profiles support
Currently, mlxsw enforces that all the router interfaces (RIFs) have the
same MAC prefix.

Relax this limitation by using RIF MAC profiles. Each profile is
associated with a particular MAC prefix and multiple RIFs can use the
same profile. Therefore, the number of possible MAC prefixes is no
longer one, but the number of profiles supported by the device.

Store the profiles in an IDR and reference count them according to the
number of RIFs using them.

Associate a RIF with a profile when the RIF is created and remove the
association when the RIF is deleted.

Change the association following 'NETDEV_CHANGEADDR' events, except when
only one RIF is using the profile. In which case, change the MAC prefix
of the profile itself instead of associating the RIF with a new profile.

26029225d9 mlxsw: spectrum_router: Propagate extack further
The next patch will set the MAC profile of a router interface (RIF) as
part of its configure() callback. The operation can fail in case the
maximum number of profiles was exceeded.

Add extack to mlxsw_sp_rif_ops::configure() in order to communicate such
failures to user space.

In addition, the MAC profile of a RIF can change following a
'NETDEV_CHANGEADDR' notification. Propagate extack to
mlxsw_sp_router_port_change_event() so that failures could be
communicated in this path as well.

No functional changes intended.
